Embodiment

[0058] This embodiment provides an air conditioner with water heater function, such as Figure 1 to Figure 2 As shown, it includes an air conditioner circulation system 100 and a water heater heat exchange module 200; the air conditioner circulation system 100 can drive the water heater heat exchange module 200 to work while meeting the working requirements of the air conditioner, which can not only meet the user's demand for the air conditioner, but also Meet the needs of users to use water heaters.

[0059] The air conditioner circulation system 100 includes a compressor 110 , a four-way valve 120 , an indoor heat exchanger 130 and an outdoor heat exchanger 140 .

[0060] The compressor 110 is sequentially connected to the indoor heat exchanger 130 and the outdoor heat exchanger 140 through the four-way valve 120 to form a refrigeration circuit or a heating circuit. The air outlet of the compressor 110 communicates with the four-way valve 120 through the first exhaust pipe ...

specific example

[0105] Specific examples, such as when T p When the temperature is greater than 50°C, open the first control valve 240 directly, when T p When the temperature is less than 50°C, the frequency of the compressor 110 is controlled so that the first control valve 240 is opened after the exhaust gas temperature reaches 50°C.

[0106] Such as Figure 12 As shown, sub-step three: when the first control valve 240 is in the open state, detect the actual temperature of the water in the water tank 210 to obtain the second water temperature T 实际2 , based on the second water temperature T 实际2 and preset temperature T 预设 As a result of the comparison, the opening degree of the first control valve 240 is controlled to control the flow value of the bypass pipe.

[0107] Specifically: when the second water temperature T 实际2 with preset temperature T 预设 When the difference is greater than the first threshold ΔT1, the opening degree of the first control valve 240 is controlled to the first...

Abstract

The invention discloses an air conditioner with a water heater function and a control method, and relates to the technical field of air conditioners. The air conditioner comprises an air conditioner circulating system and a water heater heat exchange module, wherein the air conditioner circulating system comprises a compressor, a four-way valve, an indoor heat exchanger and an outdoor heat exchanger; the compressor communicates with the indoor heat exchanger and the outdoor heat exchanger in sequence through the four-way valve to form a refrigerating loop or a heating loop; an exhaust port ofthe compressor communicates with the four-way valve through a first exhaust pipe; the first exhaust pipe communicates with a secondary compression module connected with part of pipes in parallel; a refrigerant inlet of the water heater heat exchange module communicates with the first exhaust pipe, and is positioned on a pipe between a refrigerant outlet of the secondary compression module and thefour-way valve; and the refrigerant outlet of the water heater heat exchange module communicates with a pipe between the outdoor heat exchanger and the indoor heat exchanger. When the air conditioneris used, the air conditioner uses high-temperature exhaust of the compressor for providing heating heat to a water heater under different operation states to adjust the temperature of the water heater.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner with a water heater function and a control method. Background technique [0002] The water heaters currently used by users are mainly electric water heaters, including storage-type electric water heaters and instantaneous electric water heaters. Among them, storage-type electric water heaters need to be preheated before use, and the waiting time is relatively long. The power consumption is relatively large; the instant electric water heater produces hot water quickly, the amount of hot water is not limited, and can provide hot water continuously, but its high power will still cause large power consumption. [0003] The existing Chinese invention patent application with the publication number CN110296520A that can be referred to discloses a method and device for air-conditioning refrigeration and water heater instant heat storage heating and control.
